CAN-CRIMPING MACHINE.

SPECIFICATION forming part of Letters Patent No. 624,879, dated yMay 9, 1899. Application iled January 26, 1899. Serial No. '7Q315l'7- (N0 111051810 To zr/ZZ whom, t may concern: l

Beit knownthat I, CHARLES W. SLEEPER,

of Coos and State of New Hampshire, havey invented a new and useful Can-Crimping Machine, of which the following is a specification.

My invention relates to improvements in that class of crimping-machines in which the cans are grasped by opposing rotating disks and the flanges of the loosely-fitted can-heads are sprung or crimped firmly ,upon the canbody by rollers which press upon the flange of the can-head as the can rotates; and the objects of my invention are, first, to provide means for conveying the cans, with looselyfitted heads, to the crimping mechanism and to prevent the heads from falling oft while being so conveyed; second, to provide means for automatically grasping the cans between opposing revolving disks or chucks and compensation for variation in length of the cans, and, third, to provide convenient means'for adjusting the crimping-rolls to bear properly upon the flanges of the can-heads. I accomplish these objects by means of themechanism illustrated in the accompanying drawg Fig. 2 is a side view of the same.

ings, in which* Figure 1 is a front view of my invention. Fig. 3 is a detail showing front view of sprocket-wheel and means for moving same. Fig. 4 is a side view of Fig. 3. Fig. 5 is a detail showing front View of chuck and mechanism by which it is moved. Fig. G4 is a side view of Fig. 5.

Fig. 7-is a detail showing front view of crimping-rolls and mechanism for operating same. Fig. S is a side View of Fig. 7. Fig. 9 is an enlarged detail of chucks and can, showing position'of crimping-rolls.

1 is a column or frame of machine provided with suitable .bosses or hubs acting as jourat uniform distance from the bar 5, upon which the chain moves.

6 6 are side rails to guide the cans and prevent the heads from falling OEE.

The chain-Ll, bar 5, andrails 6 6 are made of any convenient length, and an idle-wheel (not shown) must beprovided to support the chain and guide it to the bar 5.

. 7 is a sprocket-.Wheel (see Figs. 3 and 4) secured to the shaft 8, journaled in the col'- umn 1. l i

. 9 is an arm upon the shaft S, carrying a pawl 10, which is held up against the side of the wheel 7 by a spring 11 and engages suitable notches in sideof said wheel.

12 isacam, 13 acam-rod, and 14 a'n eccentricpin passing through the -end of cam-rod 13 and engaging the arm 9 to oscillate it on shaft 8 and give continuous intermittent motion to wheel 7. The working length of camrod 13 may be changed by turning the eccentric-pin about in the end of the rod and. securing it at different positions.

15 15, Figs. 1, 5, 6, and 9, are disks or chucks fitting the heads of the canlfi and arranged to grasp the can between them and cause it to rotate as the chucks revolve. The chucks 15 15 are secured to the shafts 17 17, one of which is journaled in a sleeve 1S, adj ustably secured in column'l. The other is journaled in a sleeve 19, sliding in column l and pro, vided with rack-teeth engaged by a segmentpinion 20.

,21 is a cam, and 22 a cam-rod engaged by the cam and provided with a sliding block 23 and compression-spring 24, resting upon the block.

2 5 is an arm secured to the pinion 2O by a pinch fit and provided with a'pin 26, passing through the block 23. A downward motion of the cam-rod 22, Fig. 5, will cause the sleeve 19 to move, and thus grasp the can 1G between the opposing chucks 1515, Fig. 1, the

block 23 and spring 24 compensating 4for va- V p body as the can rotates. The rolls 27 revolve loosely upon eccentric shafts 2S 28, journaled in column 1. Arms 29 29 are adjustably secured to shafts 28 2S by pinch fits, and links 30 30 connect the ends of the upper and lower arms 29 29 together.

31 31 are cams, 32 32 cam-rods, and 33 33 eccentric-pins adjustably secured in the ends of the cam-rods by pinch fits and engaging the arms 29 29 and links 30 30. Pins 34 34 project from the pins 33 33 for the convenience of moving the same. A movement .of the parts from the position shown in Fig. 8 causes the lower crim ping-roll to rise and the upper crimping-roll to descend. The crimping-rolls are first setto bear equally upon the can-head, as in Fig. 9, and the length of the cam-rod 32 is then changed by moving the eccentric-pin 33 until the desired pressure upon the can-head is obtained.

In operation the can-bodies with the heads on are placed upon the chain 4 and between the guide-bars 6 6. The continuous intermittent motion of the chain 4 brings them one at a time in alinement with the chucks 15 15, which grasp the can and rotate it, and While the chain remains stationary the crimpingrolls press upon the flanges of the can-heads and spin them upon the can-bodies. As the crimping-rolls and chucks release the can the chain moves forward, carrying the crimped can into a chute 35, from which it may be rolled to any suitable receptacle.

NVhat I claim as my invention, and desire to secure by Letters Patent, is-

1. In a can-crimping machine; the revolving chucks arranged to grasp and rotate the can and crimping-rolls arranged to crimp the flanges of the can-heads upon the can-bodies, combined With the chain composed'of links having projections to push the cans along and sloping sides upon' which the cans rest, a horizontal support for the chain two parallel guides to guide the can and prevent the can-heads from falling off, and means for imparting continuous intermittent motion to the chain to bring the cans in alinement with the revolving chucks, all substantially as described, and for the purpose set forth.

2. In a can-crimping` machine; the revolving chucks, a chain arranged to carry the cans and place them in alinement with the chucks and crimping-rolls arranged to crimp the heads upon the cans, combined With the sleeve 19 carrying one of the revolving chucks the pinion 20, arm 25, cam 21, and cam-rod 22, to give reciprocating motion to the sleeve; the cam-rod being provided with a sliding block 23 engaged by the arm 25 and a spring 24 resting upon the said block and yielding under variation in the length of the can-bodies grasped by the chucks, substantially as described and for the purpose set forth.

3. In a can-crimping machine the combination of revolving chucks arranged to grasp and rotate the cans, and means for placing the calls between the chucks, with crimpingrolls arranged to bear diametrically opposite each other upon the flange of the can-head; the rolls being mounted upon eccentric shafts, and With means for oscillating the eccentric shafts to cause the crimping-rolls to press upon the flange of the head of the rotating can, substantially as described and for the purpose set forth.

4. In a can-crimping machine; the revolving chucks to grasp and rotate the can, means for placing the cans between the chucks and crimping-rolls mounted upon eccentric shafts and arranged to bear diametrically opposite each other upon the flange of the can-head, combined With the arm 29 and link 30 to conneet the eccentric shafts, and with the cam 31 and cam-rod 32 to give oscillating motion to the eccentric shafts, and With the eccentricpin 33 connecting the cam-rod with the link 30 and one of the arms 29 as a provision for varyingthe Working length of cam-rod by turning the eccentric-pin, substantially as described and for the purpose set forth.

5. In a can-crimping machine; the revolving chucks arranged to grasp and rotate the can, crimping-rolls to roll upon the flanges of the canheads and a conveyer-chain to carry the cans to a position in alinement with the chucks, combined with the sprocket-wheel 7, to move the chain, the latch-carrying arm 9 to engage the sprocket-Wheel, and the cam 12 and cam-rod 13 to move the arm, the camrod being provided with an eccentric-pin 14 engaged by the arm 9, all as substantially described and for the purpose set forth.
